Okay so im 17 years old, and over the past 2-3 months my body just doesnt feel the same. I KNOW sometging is wrong i just dont know what, the abdominal cramping has just started over the past 2 weeks. It never stops. Constant discomfort all day with random spurts of pain! Im gassy, alot of burping and farting. The headaches come every few days sometimes 2 days in a row. I almost never poop... it used to be i was constipated for about a weekvorbso and then i would have violent diarrhea, now its constipation for about 2 weeks and then finally when i do poop its just as big as a rabbits! I eat ALOT so where is all the food going!?
